Cart abandonment is frustrating, but fixable. First, remove unnecessary steps and let users check out as guests. Offer multiple payment methods, including PayPal, Apple Pay, and Buy Now, Pay Later options. Use cart recovery emails with incentives to bring shoppers back. Add a persistent cart feature so items stay saved across devices. Exit-intent popups with a discount also work wonders. Lastly, build trust with security badges and social proof. Your customers must feel safe entering payment details.
